Answer:
5√202
Step-by-step explanation:
By Pythagoras theorem,
x^2 = 45^2 + 55^2
= 2025 + 3025
x^2 = 5050
x = 5√202

Step-by-step explanation:
Answer:
96 sq. cm.
Step-by-step explanation:
A "kite" has 2 diagonals, which are the "width" and "height" of the kite.
Using diagonals, the area of a kite is given by 
Where
A is the area
p,q are the width and height, respectively
From the problem given, p is 12 and q is 16, so the area is:
Thus, the area is 96 sq. cm
Answer:
12/10=1.2
Step-by-step explanation:
You just move the decimal one place value to the left. so 12÷10=1.2 which is the same as 12/10=1.2
Answer:
The answer to your question is: B and D are correct
Step-by-step explanation:
Remember that the sum of the internal angles in a triangle equals 180°.
The sum of supplementary angles equals 180°
Then
(6x + 1) + (4x + 5) + [180 - (8x + 30)] = 180
6x + 1 + 4x + 5 + [180 - 8x - 30] = 180
10x + 6 + 150 - 8x = 180
2 x = 180 - 156
2x = 24
x = 24/2
x = 12
∠JKL = 4(12) + 5 = 48 + 5 = 53
∠KJL = 6(12) + 1 = 72 + 1 = 73
∠KLJ = 180 - 73 - 53 = 54
∠KLM = 126
